Dorsal nerve of the penis

Nerve: Dorsal nerve of the penis
Pudendal nerve, its course through the lesser sciatic foramen, and branches, including dorsal nerve of the penis at bottom left.
Transverse section of the penis. (Dorsal nerve visible at top.)
Latin	nervus dorsalis penis
Gray's	subject #213 968
From	pudendal nerve

The dorsal nerve of the penis is the deepest division of the pudendal nerve; it accompanies the internal pudendal artery along the ramus of the ischium; it then runs forward along the margin of the inferior ramus of the pubis, between the superior and inferior layers of the fascia of the urogenital diaphragm.

Piercing the inferior layer it gives a branch to the corpus cavernosum penis, and passes forward, in company with the dorsal artery of the penis, between the layers of the suspensory ligament, on to the dorsum of the penis, and ends on the glans penis.

It innervates the skin of the penis.
